Even worse. I'm pretty sure Lubbock is in a dry county.
Lubbock is NOT a dry county anymore. However there isn't much there for good beer wise since it is a college town, although I graduated and moved away I still go back a few times a year.
That being said in Lubbock Triple J Chophouse is Lubbock's only brew pub and its got some pretty decent beers plus the food is pretty good. If you go to crickets off Main Street right across the street from Texas Tech's Campus (GUNS UP!) its a decent beer bar but last time I was there I didn't find much local or Texas. I haven't lived there since I graduated but as far as I remember those are your best bets for beer bars/restaurants. Although the fox and hound on 82nd street had a pretty good tap selection. I do know that there is a new brewery in Wolfforth (15 min SW) called Wicked Beaver but I don't think its open to the public so your best bet is to find there beer in a bar.
In DFW its a little tougher, DFW IS HUGE. I live on the SW side of Fort Worth and it takes over an hour to get to downtown Dallas. However as for a list of good breweries here's my picks: Martin House (Ft Worth), Peticolas (Dallas), Deep Ellum (Dallas), Armadillo Aleworks (Denton), Rabbit Hole (Justin), Lakewood (Dallas), Revolver (Granbury), Four Corners (Dallas), Firewheel (Rockwall), and Rahr (Ft Worth, and his family owns Rahr Malting company).
If you are staying in Fort Worth I recommend Wired Willy's its a hole in the wall tap house but he's got a pretty good selection and at least half of his taps are local/Texas beers (no food but there is a taco truck out back).
Where are you staying for the wedding? It might help to guide you better to some of the recommended places. BTW most breweries are only open to the public on Thursdays and Saturday's for tours, no tasting rooms in north Texas that I know of since the laws just changed to allow them to have tasting rooms.
